PLOW ATTACHMENT.

Application filed May 20,

This invention relates to improvements in plow attachments and more particularly to the standard used in connection with the gage wheel.

()ne object is to provide such an attachment that can be readily attached to or moved from the plow beam and that requires no bolts or other fastening means that tend to weaken the beam in their application.

A further object is to provide such an attachment that is cheap to manufacture, eflicient in operation and of simple construction.

Vv' 1th the foregoing and other objects in view the .invention consists in the combination and arrangement of parts to be hereinafter fully described, particularly pointed out .in the claims and illustrated in the accompanying drawings which form a part of this application and in which- Fig. l is a perspective view of a plow illustrating the application of the attachment to the plow beam.

Fig. 2 is an enlarged view of the attach ment in side elevation illustrating its attachment.

Fig. 3 is a front view of Fig. 2.

Fig. 4t is a fragmentary view of Fig. 3 illustrating the manner of assembling the attachment.

Like reference characters denote corresponding parts throughout "the several views.

The reference numeral 1 denotes the beam of the plow which is provided with the clevis 2, plow share 3 and handles at. The attachment comprises an oblong plate 5 of the same width as the plow beam, one side of said plate being roughened or corrugated to enable it to bite into or obtain a purchase frictionally upon the plow beam.

At obliquely opposite corners of the plate 5 but rising from the longer edges thereof are the lugs 'i' curved in opposite directions and their relatively adjacent edges being arcuately recessed. At the remaining corners, or contiguous thereto, are the laterally extending lug rests 8, 9 that extend in a common direction for supporting engagement with the beam.

The said plate 5 is formed further with the integral depending tongue 10 one lateral edge thereof being formed with the recess ll, said tongue extending away from one of the longer edges of the plate and lying in a common plane therewith. The plate is 1927. Serial No. 192,927.

forn'ied centrally with a perforation 12 which in a straight line with a similar perforation 13 formed in the tongue, the perforation 12 being threaded.

The standard let is provided with the gage wheel l5 and is formed with a plurality of perforations 16 all lying in a straight line and spaced equidistant one from the other and so formed and spaced, further, that when the standard is disposed against the plate 5 with one perforation 16 in alignment with the plate perforation 12 one perforation 16 will also be in alignment with the perforation 13.

With the standard 1 f disposed fiat against the plate 5 and one perforation 16 aligned with the perforation 12 a screw 17 is em ployed to connect said members, the threaded inner end of the screw engaging the threads in the perforation l2 and a stud 18 clmnecting the perforate portions 16, 13 of said members. The stud 18 is formed with a reduced head 19 that extends through a flat spring 20 secured at its upper end by rivet 21 to the tongue 10, the lower and rounded end 22 of said tongue being connected by the hinge 23 to said tongue so that the rounded end of the spring can be moved a limited distance away from the tongue. This movement accomplished by pressing the free end of the stud 18 toward the sprlng.

A clamping hook has the free ends 25, 26 of its sides bent until they project upon opposite sides of the base. This hook is applied to the beam, the base of the hook being disposed obliquely of the beam, the sides of the hook passing over and under the beam and plate 5 and being disposed in the recessed portions of the lugs 6, 7, the ends 25, 26 of the hook extending partially across the standard 14.

In securing the attachment to the plow beam the plate 5 is first applied and held in position until the hook 24: is applied. The standard 14 is then applied directly to the plate 5, first in an oblique position with the upper end of the standard disposed toward the rear end of the beam as shown in Fig. l, the standard is then swung intovertical position when its lateral edges will pass beneath the ends 25, 26 of the hook the stud 18 being then disposed in a perforation 16 of the standard. To release the standard from the stud 18 to raise (lower or remove the standard the stud is pushed out of engagement with the standard which is then A somewhat U-shaped moved and when an adjustment is made the stud is re-inserted in the standard. The hinge 23 will permit removal of the stud from the standard without removal from the tongue.

lVhat is claimed is:-

1. In a plow attachment, a plate, lugs for said plate, a tongue integral with said plate, a hook adapted to pass about the plow beam and engage the lugs and body portion at said plate, a wheeled standard, and fastening means for releasably connecting said standard to said plate and tongue.

2. In a plow attaehi out, a plate, lugs for said plate, two of said lugs being recessed, a tongue integral with said plate, a hook adapted to pass about the plow beam and said plate and to engage the recessed portions of said lugs, a wheeled standard, and adjustable fastening means releasably connectingr said standard to said plate and tongue.

3. in a plow attachment, a plate, lugs for said plate. two of said lugs engaging the plow beam, the remaining lugs being re.- versely curved and recessed. a tongue integral with said plate, a hook adapted to pass about the plow beam and plate and to engage with the recessed portions of said hooks. a spring com'xected at one end to said tongue. a wheeled standard, a screw connecting; said standard and plate, and a stud releasably eoni'iectiug said standard to said tongue and spring.

l. In a plow attachment, a plate, beamengaging lugs formed upon said plate, recessed lugs l'ormed upon said plate between said lirst. named lugs, a tongue integral with said plate, an U-shaped hooh adapted to pass about the plow beam and said plate with its sides engaging the said recessed hooks, a flat spring connected at one end to said tongue, a wheeled standard, a screw connect ing said standard and plate. a stud releasabiy connecting said standard to said tongue and spring, and a hinge conncelil'lg said spring and tongue.

in a plow attachment. an oblong plate having one corrugattal tare, beam-euga ing lugs 'lormed upon said plate, reversel r curved lugs formed upon alternate corners of said plate, a tongue integral with said plate, a substantially U-shaped hook adapted to pass about the plow beam and plate with its sides engagiiu;- with the recessed lugs. the ends of said sides being bent in opposite directions. a Hat sprint! riveted at one end to said tongue. a wheeled standard formed with a plurality ol spared perforations, a screw adapted to connect an of the perforate portions ol said standard and said plate. a stud relcasablv connerlin; the rccussed portions ol said standard to said tongue and spring. and a hinge ('(Hllllt'llfll! said tongue and spring.

in testimony that I claim the l'oregoing as my own 1 have hereto allixed my signature.
